Facebook took on Etsy and eBay in 2016 with the launch of Marketplace, a feature within the main Facebook app that you can use to buy and sell goods. We've seen it work really well on a local basis because it's so simple to see free and paid-for items that are around where you live - and around the stuff you're interested in. Before Marketplace, people used Facebook Groups to buy, sell, trade, and barter. You could set up a garage sale-type group for your community, for instance, so that people in your local neighborhood could post things they had for sale and look for items from others. It was a bit clunky though, with Marketplace offering a much more streamlined approach. Here's everything you need to know about Facebook Marketplace, including where to find it, how to sell items along with how to make purchases safely.
